Specification of Letters Patent.

Patented Nov. 23, 1525.

Original application filed April 28, 1911, Serial No. 623,834. Divided and. thisapplication filed November To all whom it may concern Be it known that L'JOSEPH BIJUR, a citizen of the United States, and a resident of the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Electrical Apparatus, of which the following is a specification. I

This invention relates to electrical apparatus for motor vehicles of the'general' type set forth in my copending application Serial No. 623,834 filed April 28th, 1911, which issued on November 20th, 191?, as Patent No. 1,246,852, of which the present application is a division.

One, of the objects is to provide controlling apparatus in a system of the above type which will under all conditions of operation, distribute a current having proper characteristics for efiicient operation.

Another objectis to provide apparatus of the above type which shall be sensitive to changesin condition of operations of the system, and whose action shall be automatic.

Another objectis to provide apparatus of the above type simple and rugged in construction, and which may easily be kept in operative condition.

Other objects will be in part obvious and in part pointed out hereinafter. v

The invention accordingly consists in the 'features' of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application which will be indicated in the following claims.

In the accompanying drawings, wherein is shown one of variouspossible embodiments of this invention:

Figure 1 is a detail elevation of a regulating device. i Fig. 2 is an end view thereof.

" Fig. 3is a'detail sectional view of a contact mechanism involved in the regulating device of Fig. 1.

Fig. 4: is a detail view of the contact holder of this mechanism.

Fig. 5 is a detail side elevation of a circuit making device Serial No. 200,885.

Fig. 6 is an end view thereof.

Fig. 7 is a detail plan of a supporting element.

Fig. 8 is a sectional view taken along the line ZZ of Fig. 7.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring to Figs. 1 to f of the drawings there is provided a magnet 53 having a core 54L formed with an enlarged head or end 55. Secured to the opposite end of core 54 is a support 56 bearing a pivoted iron member 57 which has at its free end an armature 58 retracted from core 54 by an adjustable spring 59. Mounted upon the magnet adjacent the head is a brass member or bracket 60. As shown in the drawings, the brass member or bracket 60 is mounted so as to be insulated from the magnet 53 and its core 54. Specifically describing this detail, it is noted that the core 54 has a reduced diameter 54. immediately below head .he brass member 60, and the disk 20 contacting the lower arm thereof, have openings 21 through which portion 54- of the core extends, these openings being of larger diameter than said reduced portion which is consequently spaced from the members 20 and 60. An insulating disk 22 prevents electrical connection between member 60 and the magnet 53, and a second insulating disk 23 maintains the head 55 out of electrical contact with member 60. Formed upon 'inember 60 is a resilient cross-piece 61 provided with a pin 62 having an enlarged head. A similar pin 63 is mounted in the brass pm Get, with which the armature 58 is provided, as best shown in Fig. 3 of the 67 communicating with slot 68 at each end.

Within these openings are inserted the contact members 69, each of which is formed with a shoulder 70. These contact members are inserted within the openings 67 in spring 55, and the slipped into position in which it is held by its frictional contact with the parts with which it engages. The contacts are thus readily removable and are yet securely mounted in position ant, are adapted as the armature vibrates to make and break the circuit at two points. The armature 58 provided with counterweight '71 whereby its action is r l stantially independent of the effect of tin tion and gravity. Tillie distance between the contacts upon meinber Gil and these i t the armature is adjusted by a screw 72 vided at the tree end of the member 60, and it may be noted that the latter in well as the contacts tiereon are i from the armature. By this arr-a1 there are pro ided two parallel cor were, so that in the event of one becoming worn or pitted, the other may maintain eliicient action of the device, and also the resilient mounting of the contacts affords a rubo g action as they are engaged by the armature which tends to keep them clean and insure a good electrical connection. 7

Referring now to Figs. 5, 6, 7 and 8 of the drawings, there is shown a main switch which governs the electrical connection of the generator with the external circuit consisting of battery and translating devices. This switch comprises a magnet 73 which may have several windings and is provided with a core having an enlarged head 74. Secured to the opposite end of this core is a supporting member 7 5 having pivotally connected thereto a balanced armature 76. This armature bears a removable slotted contact 77 coacting with a fixed contact 78, these parts being so insulated and connected as to control connection with the external circuit. The supporting member 75 is secured to a brass piece 79 which holds it in position and spaces it from the supporting wall indicated at 80, and between these parts is positioned an adjustable retracting spring 81 tending to swing the armature away from the core to a distance limited by a brass stop 82 held beneath the magnet core and extend ing over the armature as at 83.

It will thus be seen that there is provided apparatus of a compact, and yet simple, construction in which the several aims of this invention are achieved.

As many changes could be made in the above construction and many apparently widely diiferent embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shownin the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. i

It is also to be understood that the language used in the following claims'is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent is: V

1. In apparatus of the class described, in combination, a magnet, a movable member mounted to be attracted thereby, a bowspring mounted upon said member and bearing a pair of replaceable contacts respectively adjacent its ends, said spring being formed and positioned to make a connection for said contacts as said movable member moves, and means adapted to retract said movable member from said magnet.

2.
